Raytheon 6SN7GTB Black Plate Matched Pair NOS 6SN7

This is a well matched pair of Raytheon 6SN7GTB vacuum tubes, that were made in Japan. Both tubes test very close to each other. They have a slim base and are in a short glass envelope. They both have black plates, side getter, and yellow lettering. They getters look a little worn, but these tubes still test strong and should have plenty of life left in them. Regardless, they are priced accordingly. These are highly sought after Raytheon 6SN7GTB tubes, act quickly before they sell out! More available upon request.

Be careful buying tubes from sellers who list tubes as matched if they do not provide test results or the equipment that they tested their tubes on.

I personally tested these tubes on my recently calibrated Hickok 600a and my TV7D/U and the results are as follows:

2,575/2,150
2,600/2,300
